|
|
* hooks in WordPress to change core functionality.
|
|
|
|
|
*
|
|
|
|
|
* When using a child theme (see http://codex.wordpress.org/Theme_Development
|
|
|
|
|
* and http://codex.wordpress.org/Child_Themes), you can override certain
|
|
|
|
|
* functions (those wrapped in a function_exists() call) by defining them first
|
|
|
|
|
* in your child theme's functions.php file. The child theme's functions.php
|
|
|
|
|
* file is included before the parent theme's file, so the child theme
|
|
|
|
|
* functions would be used.
|
|
|
|
|
*
|
|
|
|
|
* Functions that are not pluggable (not wrapped in function_exists()) are
|
|
|
|
|
* instead attached to a filter or action hook.
|
|
|
|
|
*
|
|
|
|
|
* For more information on hooks, actions, and filters,
